COLLAR-TIPPING MACHlINE Specification of Letters Patent.

Patented Aug. 6, 1907.

\ Application tiled July 15, 1904. Serial No. 216,657.

Be it knownthat 1, CHARLES A. ROYCE, a citizen of vv the United States of America, residing at Springfield,

in the county of Hampden and State of Massachusetts, have invented new and useful. Improvements in Collar-Tipping Machines, of which the following is a specification.

This invention relates to laundry machinery, and

, specifically to a machine for tipping collars, this being 10 the term applied in this art to the operation which consists in folding back the two upper corners of a fiat standing collar.

The object of the present invention is to provide a machine for tipping these collars much more rapidly and perfectly than can be done by hand and without making such a shaip fold as to injure the material on the folding line: Furthermore, the machine is so or ganized as,to fold over the corners and iron them at one operation without pressing the corners into the body of the collar, whereby it becomes outlined thereon.

This invention consists in the construction described in the following specification and clearly.

pointed out in theclaims annexed thereto,

1n the drawingsforming part of this application,- Figure 1 is a perspective view of a machine embodying the invention. Fig. 2 is a vertical section taken cured, a bearing-box b, the axis of which is vertical,

' and in which is a sliding stem 0, to the lower end of which is pivotally secured a connecting-rod d, the

lower extremity of which is properly connected with afoot-operated treadle e. Under this treadle a suitable spring, as f, may be located, whereby when the treadle is depressed to raise the stem. 0', said spring may aid in effecting the quick 'return of said stem downwardly. On the upper "end of the stem 0 there is secured thereto in a horizontal position a forked frame g, on the two parallel arms'g andgT -oi which a slg'dable collar-clamping device is supported. This devi e con sists of two clamping jaws h and h, the upper ends of which are beveled off from their meeting edges down wardly toward the outside of each jaw, said beveled off portions being lettered respectively 1' and j, and-it is between-the meeting edges of these jaws that the collar m iscla mped in such position that -a triangular section, of each end thereof will extend above this meeting edge. The upper edges of the jaws should be slightly rounded 0th The collar clamp slides back and forth toward and away from the standard a on the frame g, the jaw h h and h are hinged together by 'two arms 1* and 22 ex-.

tending from that side of the jaws next to the frame a obliquely toward one another, their free ends being united by a screw t.

By means of this construction the jaw k may be swung'away from the jaw h by meansof a suitable hau dle o, in the direction of the arrows in Fig. 1, to open the jaws for the introduction of the collar'm. Secured.

to the overhanging upper end of the frame a. is ahollo'w head 10, preferably rectangular in form, the under'surface of which has inwardly beveled sides at, whose angle conforms to the bevel oi the jaws h, h, of the collar clamp. The. beveled surfaces of the jaws and ofthis, head are smoothly polished and the apex of the beveled sides of the head 11) may either be finished off, asshown in Figs. 1 and 2, with a depending V-shaped rib y parallel with the beveled sides x of said head, or it may be p i constructed in any desired manner.

The hollow head 11) is in communication with the feed and discharge pipes 3 and 4 by which steam may be conveyed through the head to keep the latter at any desired temperature, which may be determined by the pressure oi'the steam-admitted'thereto.

The merging of the surfaces of the rib y and tho bev-. eled sides at is on a curve which represents thecurve on which it is desired to form .the told on the collar.

While steam is the preferred heating medium for the head w, any other means may be substituted therefor, but steam is by far the most convenient for the reason that a given pressure will insure a given temperature in thehead. .This isimportant in that it insures uniformity of product, as this "head not only constitutes means to press the corners of the collar against the beveled edges of thejaws of the colla'r-clamp, but it is also the ironing device whereby the surface of the back-folded e'nds oi the collar :are ironed out smooth.

V In operating this device, the clampis opened by swinging the jaw h away from the jaw h, and inserting therebetween the ends of a fiat collar which have been matched together, the collar being inserted between I thejawr-Y'in a slightly oblique position as shown in Fig. 1, whereby a triangular portion of each corner will be left upstanding therebetween the jaws are then closed.

These corners, which have been previously moistened, are then bent down by the fingers against the beveled surface oi the jaws, about as shown inFig. l, and-the closed jaws are then slid forward underthe'head w,

' whereupon the 'opemtion of thejtreadle c by the foot under surface of the head and hold it there for a mo ment long enough for the stiffening material in the collar to become, set.

The preferred construction of this machine embodies a number of these heads and elamps'in one frame, the

' treadle and connecting rod for each head being pivoted together at d to form a toggle joint. When the troadle is depressed the rod is moved into a vertical plane and after a collar has been inserted in. one clamp and forced up into the V of the head w, it may be left there under pressure while oneor more other collars are being insorted in other clamps and placed under pressure in a similar" manner. 3

If desired, the plates 5, such as are shown in Fig. 3, may be used in connection with the above described machine: and while the machine is perfectly operative without these plates, the use thereof permits a more rapid operation of the machine for the reason that with the plate interposed between the collar and the head 10 the material can not, under any circumstances, be injured, however quickly the jaws of the collar-clamps may be forced upward to the seating position under the head.

When the plates 5 are used, the central depending portion 5. thereof is inserted between the ends of the collar in the jaws of the. clamp after the collar'is placed therein, and while the jaws are held slightly apart, the plate being then pressed down by the operator, to confine the corners otthe collar between the under surface and desire to secure by Letters Patent of the'United States, is P 1. In a machine of the character described, means to' hold a collar to leave the corners thereof exposed, a suitable head to fold said-cornersbackward simultaneously toward the body of the collar, means to heatsaid head. and means to bring, the collar holding means and head into engagement with the collar. 1 0
